WASHER FLUID
Checking the washer fluid
level
The reservoir is translucent so that
you can check the level with a quick
visual inspection.
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary.
Plain water may be used if washer
fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
Checking the parking brake
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 20 kg (44 lb,
196N) of force. Also, the parking
brake alone should securely hold the
vehicle on a fairly steep grade. If the
stroke is more or less than specified,
we recommend that the system be
serviced by an authorised HYUNDAI
dealer.
Stroke : 3 notchOLF074009N
Coolant
•Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
•Radiator coolant can severely
obscure visibility when sprayed
on the windscreen and may
cause loss of vehicle control or
damage to paint and body trim.
•Windscreen washer fluid
agents contain some amounts
of alcohol and can be flamma-
ble under certain circum-
stances. Do not allow sparks or
flame to contact the washer
fluid or the washer fluid reser-
voir. Damage to the vehicle or
occupants could occur.
CAUTION

extremely dusty or sandy areas,
replace the element more often
than the usual recommended
intervals (refer to “Maintenance
Under Severe Usage Conditions”
in this chapter).
• Do not drive with the air cleaner
filter removed. This will result in
excessive engine wear.

Maintenance
Do not allow the wiper arm to fall
against the windscreen, since it
may chip or crack the wind-
CAUTION
WIPER BLADES
Blade inspection
Information
Commercial hot waxes applied by
automatic car washes have been
known to make the windscreen
difficult to clean.Contamination of either the wind-
screen or the wiper blades with for-
eign matter can reduce the effective-
ness of the windscreen wipers.
Common sources of contamination
are insects, tree sap, and hot wax
treatments used by some commer-
cial car washes. If the blades are not
wiping properly, clean both the wind-
screen and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water.
To prevent damage to the wiper
blades, do not use petrol,
kerosene, paint thinner, or other
solvents on or near them.
Blade replacement
When the wipers no longer clean
adequately, the blades may be worn
or cracked, and require replacement.
To prevent damage to the wiper
arms or other components, do not
attempt to move the wipers manu-
ally.
The use of a non-specified wiper
blade could result in wiper mal-
function and failure.

BATTERY
For best battery service
• Keep the battery securely mounted.
• Keep the battery top clean and dry.
• Keep the terminals and connec-
tions clean, tight, and coated with
petroleum jelly or terminal grease.
• Rinse any spilled electrolyte from
the battery immediately with a
solution of water and baking soda.
• If the vehicle is not going to be
used for an extended time, discon-
nect the battery cables.

Battery dangers
Always read the follow-
ing instructions carefully
when handling a battery.
Keep lighted cigarettes
and all other flames or
sparks away from the
battery.
Hydrogen, a highly com-
bustible gas, is always
present in battery cells
and may explode if ignit-
ed.
Keep batteries out of the
reach of children because
batteries contain highly
corrosive SULFURIC
ACID. Do not allow bat-
tery acid to contact your
skin, eyes, clothing or
paint finish.
(Continued)
WARNING (Continued)
If any electrolyte gets
into your eyes, flush
your eyes with clean
water for at least 15 min-
utes and get immediate
medical attention. If elec-
trolyte gets on your skin,
thoroughly wash the
contacted area. If you
feel a pain or a burning
sensation, get medical
attention immediately.
Wear eye protection
when charging or work-
ing near a battery.
Always provide ventila-
tion when working in an
enclosed space.
An inappropriately dis-
posed battery can be
harmful to the environ-
ment and human health.
Dispose of the battery
according to your local
law(s) or regulation.
